RUG LOOM Filed Dec. 10. 1953 3 Sheets-Sheet 2' INVENTOR. 5454mm? 1?: VALVA ATToRA/Er United States Patent RUG LOOM Eleanor R. Valva, Worcester,Mass. Application December 10, 1953, Serial No. 397,388 7 Claims. (CI.28-15) This invention relates to improvements in rug looms or framesused in making needle-point rugs and has for its primary object toprovide a loom which in use will eliminate squaring and blocking of therug.

A further object of this invention is to provide a novel constructionfor holding the foundation web in a taut position as the workprogresses.

A further object of this invention is to provide means for holding thesupply roller against rotation to hold the web taut as the workprogresses and to provide means for adjusting the tension on the web.

A further object of this invention is to provide means for keeping therug straight between the supply roller and the center roll.

A still further object of this invention is to provide a locking meanson the frame at each end of the loom which cooperates with means on theends of the loom to hold the loom in any desired position.

A still further object of this invention is to provide a compact, sturdyand inexpensive loom.

These and ancillary objects and structural features of merit areattained by this invention; the preferred embodiment of which isillustrated in the accompanying drawings, wherein:

Figure 1 is a front elevational view of the loom;

Figure 2 is an end elevational view thereof;

Figure 3 is an elevational view of the other end;

Figure 4 is a top plan view;

Figure 5 is a near elevational view;

Figure 6 is a transverse sectional view;

Figure 7 is a fragmentary vertical sectional view with certain partsremoved and taken substantially along line 7--7 of Figure 6 toillustrate the locking means for the loom;

Figure 8 is a sectional view taken on line 8-8 of Figure 7;

Figure 9 is a fragmentary sectional view taken on line 99 of Figure 6;and

Figure 10 is a detailed view of the tensioning means of the inner end ofthe foundation web.

Referring now more particularly to the accompanying drawings, the loom 8includes end stands 12 and 14 having bases 16 and rigidified byconnecting braces 18.

The end stand 14 is formed with a closed upper end 18 having an opening20 and the upper closed end 22 of the end stand 12 has a vertical slot24 formed in its upper portion. The loom frame 10 includes end plates 26and 28, each of which is a unitary cruciform member having arms 30 and32 connected at their ends by bars 34. The end plates are connected by arod 36. The ends of the rod 36 project beyond the end plates 26 and 28,which are fixed on the rod at the center of the arms 30 and 32.

One end of the rod 36 is journalled in the opening 20 and the other endof the rod 36 is seated in the slot 24. A center roller or take-uproller 38 is provided and includes flat elongated bars 40 and 40', whichare rectangular in cross-section and are fixed at their ends in the end2 plates and surround the rod 36. The center roller constitutes atake-up roller on which a foundation web 42 is wound.

To hold the inner end or base of the web 42 taut or under tension astarting roller 44 is provided and is attached to a bar 40' by endless.resilient bands 46. Pins 48 radiatefrom the roller 44 and terminate inhooks 50 which are engaged in openings 52 in the edge 54 of the innerend of the web 42.

A supply roller 56 is formed at its ends with flat projections 58 thatare designed to fit into axial slots 60 formed in the ends of arms 30and 32. I

To lock the loom frame 10 in adjusted positions, a locking plate 66 isfixed to the outside 'of the end plate 28. The plate 6'6 is a ring andhas circumferentially spaced peripheral slots 70. A locking pin or lug72 is hingedly mounted as at 73 on the end of the upper portion 18 ofthe end stand 14 for inward vertical swinging movement with the end ofthe upper portionfofming a stop to arrest the lug in a horizontal plane.The free end of the lug is adapted to extend into the slots 70 andarrest the rotation of the loom frame. A knob 74 is formed on the lug sothat it can be conveniently moved about its pivot.

In use, the end 54 of the web 42 is attached to the hooks 48 and isstretched taut from the supply roller 56, which is placed into the slots60 depending upon the desired tension. To permit rotation of the loomframe, the lug 72 is raised by grasping and liftingthe knob.

It will be noted that the relationship between the roller 44 and thesupply roller 56 is such that the web can be placed under any desiredtension by placing the roller 56 in the desired slots.

As seen in Figure 4, springs 76 and 78 are connected between the arms ofthe end plates 26 and 28 and the side edges of the web 42 to maintainthe web straight between the roller 44 and supply roller 56. Thus alongitudinal and transverse tension is imposed on the web 42. With thefoundation web thus kept under tension, the same may then be worked uponin conventional manner to complete the same into a hooked rug.

While the preferred embodiment of this invention has been disclosedherein, it is understood that this is the best known form so that otherembodiments may be made, as come within the appended claims.
